Battery operated self heating thermos container

Abstract

A thermos container with inner sealing cap and outer cap used to contain solid or liquid foods. Integral heating coils contained within the innermost compartment of the receptacle receives energy from the main power cord connected to the On / Off sliding switch power conductor. When the sliding switch is moved to the On position it activates the battery power to heat the integral coils to a certain temperature to warm the contents of the thermos container. With such applications the invention is a battery operated self heating thermos thus allowing for storage and heat to foods contained within the inner receptacle.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the priority of provisional application Ser. No. 60 / 465,001 filed on Apr. 25, 2003.STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT[0002]Not ApplicableREFERENCE TO SEQUENCE LISTING, A TABLE, OR A COMPUTER PROGRAM LISTING COMPACT DISC APPENDIX[0003]Not ApplicableBACKGROUND OF THE INVENTION[0004]Many food containers are provided for storage of foods solid and liquid, such containers as a thermos apply many elements to retain either a cooling effect to keep foods cold or a thermal area to retain heat as to keep foods warm. Most of these containers can only keep food stored and warm for a certain period of time. As with many thermos style containers the space provided between the walls of the outer and inner receptacles is for retaining heat to warm the contents. This method cannot keep foods or liquids warm for very long. Also foods contained in such thermos style containers tend to become stewed in the...

Benefits of technology

[0005]The operation of this invention is fairly simple, when the power switch is put to the on position, the battery sends energy to the inner heating coils. The battery being a lower voltage will only heat the coils to a certain safe temperature. The coils will then heat the inner metal container. The heat conducted will then warm the contents of the inner metal container. The outer compartment is made of a heat safe plastic thus not allowing it to heat the outside. It will remain cool to the touch. The contents will be sealed by a seal-tight cap and an outer plastic cap. The outer cap will be made of the heat safe plastic. The outer plastic cap is removed during the warming process. The inner seal-tight cap will have a steam heat release valve that is lifted to the open position to release any gases created by the contents during heating. The gas will rise up through the inner chamber of the seal-tight cap through the steam heat release valve allowing for no build up of steam heat. This design will make it safe for the consumer use. The invention is a simple and effective product designed to provide a typical thermos style container with integral heating coils. This allows the invention to not only store food and beverages but to heat it on demand.

[0006]This application will provide for heating the contents of the inner receptacle on command thus alleviating any stewing of the food contents which may occur with conventional thermos containers. Cold foods such as left overs normally eaten warm will be available for consumers heated on command without the need for any other heating method such as an oven or microwave. This reduces household waste by allowing consumers to provide meals from home while consumers are mobile or “on the go.” This said invention takes the typical thermos and adds the benefit of an outer heat safe plastic, joined with a metal inner container. Benefits of this invention are the heat safe plastic which allows for safe handling of the thermos while it is heating the contents. The inner metal container is washable to remove any residue left behind from prior usage. The battery power alleviates the possibilities of scalding or overheating the contents that would cause any injury to the consumer. Rechargeable batteries may be used to power the unit. Also the materials used to construct the invention are readily available making the invention absolutely feasible, effective, and usable. The durability of this invention is reassured by it's construction making it usable for consumers camping, fishing, construction workers, etc. The simple technology involved in this invention makes the invention very effective and capable of everyday usage by the consumer.

Problems solved by technology

The outer compartment is made of a heat safe plastic thus not allowing it to heat the outside.
